Hello, My husband and I are planning on moving to San Migel de Allende sometime in the next year. We are coming from very flat Florida where our highest point is 45 feet. We are both in good health. Could anyone tell us what to expect changing to a much higher altitude? Anyone experience symptoms of altitude sickness? How long before you found relief? What gave you relief? Do pets get altitude sickness also? Looking forward to your replies, thanks!
